2021 NISSAN ALTIMA Electrical System Problems

Passenger back locks stopped working first. Then driver side back locks. Now both driver and passenger front locks will not lock/unlock automatically. This is scary when not being able to get in/out of vehicle for an emergency. I have reviewed multiple complaints and it appears this is a very common Nissan problem that needs to be addressed before it becomes a bigger safety problem.

Vehicle Breaking on Its Own While Driving I am writing to file a formal safety complaint and to demand immediate corporate intervention regarding an extremely dangerous mechanical/ADAS defect. My Nissan Altima has serious, ongoing safety issues where the vehicle will unexpectedly and aggressively apply the brakes on its own while I am driving, including on highways and regular roads. This defect happens without my input, without warning, and creates a major risk of being rear-ended, losing control of the vehicle, or causing a serious accident. This issue is Not minor. It is a life-threatening malfunction that makes the vehicle unsafe to operate. I have taken the vehicle to authorized Nissan dealerships for diagnosis and repair on multiple occasions & originally they told me it should be under warranty & when they spoke to the dealership they said it did not qualify under the warranty nor the extra insurance purchased &...

Hi this is in reference to my 2021 Nissan altima. The fob key entry and electrical door control doesn't work. The automator for my doors have had to be replaced. First the rear passenger and five days later the rear passenger door on drivers side and now the drivers door. As a single female this is a safety issue. If I can't access my vehicle in an emergency it turns into a life or death situation. I've researched this and many owners of like vehicle have had this complaint and reported it, but appears that Nissan has ignored it. When my repairs are done it isn't inexpensive. Please please please!!! Look into this. Please and thank you. Tempe dodge chrysler and jeep Tempe Az is where the repairs are done. Jon (833) 552-1518 service department

Rear Crash warning comes on when stopped at light , or when car is put in reverse and nothings there . also wiper refill warning. stays on even when full. Has been reported to dealership more than once also hear clicking at speeds over 50 mph.

About a month ago I noticed my backup camera had gotten dark. I didn’t worry much about it until it started glitching a couple days ago. I gave it a couple of days thinking it would go away but it hasn’t. It either glitches with lines through it, it freezes, or goes black altogether. I then did some research on it finding that there have been recalls on the 2021 nissan altima model cameras, just not mine specifically. I’m not sure why that is but it’s an issue I’m not willing to pay out of my pocket knowing that it’s been a year to model issue in the past. I would like this recall to be put in place and me be able to get it repaired free of charge seeing that it’s an obvious danger while backing up and the fact I did not personally damage it.

Stating that something is malfunctioning and see owners manual

Purchased the car in June of 2024 with around 33,000 miles. I thought the doors were locked and someone was able to just open my back door when my car was unattended in a store parking lot; the car was supposed to be locked. Lights and horn started going off. Being a female with a child this is a very scary issue. The idea that anyone can get in when you think the doors are locked or vice versa, in the event of an emergency no one can get in because the doors dont unlock. It started with the passenger side rear door lock not working with fob or button. The lock needs to be done manually. The dealership looked at it and said they could not replicate the problem and everything was working. Now both rear door locks dont work with the buttons or the key fob. The rear...

I was driving with my child in the car and the volume on the radio spiked to an extremely high level. This has happened multiple times and the volume control knob is defective so I cannot turn down the volume or the radio off. I brought the vehicle into the Nissan dealer and they diagnosed an internal failure to the A/V control unit and recommended replacing this. When the volume spikes to full blast, I cannot turn the radio off. They are charging $2000 to have this repaired even though it's a safety hazard and I am distracted while driving to keep trying to turn the volume off or the radio off. The controls do not work and they independently turn the volume on full blast.

Passenger door won’t unlock at all

Due to the Pasadena wildfires the car has been highly affected due to the extreme heat and the ashes

The passenger side door won’t unlock at all. By remote nor manually.

The car rear impact warning comes on when driving this has happened at least 5 times Also the windshield washer fluid light comes on even though the reservoir is full

Based on comments from various post online, it is a common issue that the doors’ lock on altimas with no warning or reasoning just stop working. Whatever position the lock is in, is the one that the lock will stay on even if a safety feature that’s advertised and you expect is for the Altima to automatically lock up when you begin to drive. At this point my personal Altima has not been inspected or fixed by anyone, just a day to day experience of having to check my backseat before getting in to make sure no one is in the back of my car because the doors do not lock. It’s been since about February that the car doors locking mechanism will not engage on two of my car doors, even if you press the lock/unlock switch inside of the door, the lock/unlock button on the key fob, nor...

3out of 4 door lock actuators went out .three of the doors can’t be locked from driver side and don’t automatically lock when the car is being driven.problem has been confirmed by an independent center.there were no prior warnings.

The contact owns a 2021 Nissan Altima. The contact stated that while driving approximately 25 MPH in a rainstorm, the automatic emergency braking system warning light illuminated, however, the vehicle failed to stop. The contact continued to drive and noticed that once they cleared the rainstorm the warning light disengaged. The contact informed the dealer and was informed that the repair was not covered under warranty. The contact had not taken the vehicle to the dealer to be diagnosed or repaired. The contact stated that the failure was related to NHTSA ID Number: 10207869 (Electrical System, Forward Collision Avoidance). The manufacturer was made aware of the failure and informed the contact that the rainstorm could have caused water to enter into the sensors for the automatic emergency brake to become defective. The approximate failure mileage was 17,000.

While driving home from work I experienced my fourth or fifth malfunction error flashing across my digital display. It scares me because this time is different. This time the flash made the seat vibrate and before I had a chance to react, I totally lost control Of my steering even though I had my hand family placed on each side of the wheel none of my maneuvers resulting in the tires moving in any direction. I was trying to straighten myself out but the trajectory Steered me to the right side of the road and up over the curb which tore out my front end And, had it not been for my superb braking skills, id be headfirst into a big cement hole on the side of the road. Brakes We’re locked out until I pressed on them 15,000 times it seems. Fortunately I am the only one hurt, I’m...
